[Tagging] Map a divide?

2018-10-04 Thread Kevin Kenny
In some maps that I render, I want to show the divide between a couple of major river basins. (I have a good DEM for the area in question and can derive the line readily.) In light of the recent thread on topographic prominence, I wonder if this is sufficiently interesting information at least to

The definition in the wiki is a bit contradictory, in my opinion. On the one side, it states the thing about that the arrows should point away from the saddle point towards the peaks, like steps or a oneway street, on the other side it describes a ridge to connect several peaks and saddle points

A land form ridge too me isa long, narrow raised part of a high edge formed by hill/mountains and there associated bits. A land form of a dividing range or continental divide does not have to be narrow, The 'dividing line' marks the separate water flow from one side to the other and should be 'l

Sounds sensible to me. If JOSM and ID support man_made=tower + tower:type=communication with a preset, it won't be any more work than typing in a single tag. Does this require a proposal process? How does something become officially deprecated? On Fri, Oct 5, 2018 at 2:59 PM Graeme Fitzpatrick wr
